Can't watch DVD
by jan.maske＠abwesend.de 23 May '14

23 May '14

Hi I bought a new DVD, but can't watch it. Using libdvdread 4.2.0 lsdvd eats a lot of memory and gives the following messages: $ lsdvd libdvdread: Using libdvdcss version 1.2.13 for DVD access *** libdvdread: CHECK_VALUE failed in ifo_read.c:1251 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** *** libdvdread: CHECK_VALUE failed in ifo_read.c:1980 *** *** for pgci_ut->nr_of_lus < 100 *** Please send bug report - no VTS_TMAPT ?? *** libdvdread: CHECK_VALUE failed in ifo_read.c:1251 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** *** libdvdread: CHECK_VALUE failed in ifo_read.c:1980 *** *** for pgci_ut->nr_of_lus < 100 *** Please send bug report - no VTS_TMAPT ?? *** libdvdread: CHECK_VALUE failed in ifo_read.c:1251 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** With a more recent version from git it doesn't use that much memory and outputs just: $ lsdvd *** libdvdread: CHECK_VALUE failed in ifo_read.c:1246 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** *** libdvdread: CHECK_VALUE failed in ifo_read.c:1246 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** libdvdread: Invalid IFO for title 2 (VTS_02_0.BU). Can't open ifo 2! And mplayer produces: Playing dvd://2. There are 99 titles on this DVD. There are 1 angles in this DVD title. *** libdvdread: CHECK_VALUE failed in ifo_read.c:1246 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** *** libdvdread: CHECK_VALUE failed in ifo_read.c:1246 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** libdvdread: Invalid IFO for title 2 (VTS_02_0.BU). Cannot open the IFO file for DVD title 2. No stream found to handle url dvd://2 I tried it on different computers, so it is not a hardware problem. Only one Window Media Player could actually play it. Any help would be appreciated. Jan

Strange DVD playback skip/freeze
by Tuomo Sipola 29 Apr '14

29 Apr '14

Hello, Summary: DVD playback freezes (or skips) on a physically OK disc. Is it a libdvd* problem? I have a DVD disc, Buffy 7th season R2 disc 6, which exhibits strange beahavior during the first episode, "Touched". I have tested with two different discs from different boxes. I have also checked the disc with dvdisaster, so it is not a physical problem. The same problem occurs with VLC, mplayer and totem. Video playback freezes at 32:08 and depending on the player freezes for a long time (VLC) or jumps to 33:15 with blocky things briefly on the screen (mplayer). If I go to 32:09, the playback continues normally. Rewinding back to 32:08 freezes playback again. I am wondering if this is something that could be remedied with more lax error checking or somehow by jumping a few frames ahead. The problem appears to be confined to such a small time frame that detecting the problem and just jumping to the next working part would be OK. It might be that there is an encoding problem in the video stream itself. However, I find it strange that such a problem would freeze the whole DVD playback. My question would be, is this a libdvdread or libdvdnav problem and could it be possible to fix such a problem. Also, any other pointers towards a solution would be appreciated. VLC -vvv output just before the freeze (such output is not encountered elsewhere in the log): [0xab900828] dvdnav demux debug: DVDNAV_NOP [0xab900828] dvdnav demux debug: DVDNAV_CELL_CHANGE [0xab900828] dvdnav demux debug: - cellN=13 [0xab900828] dvdnav demux debug: - pgN=13 [0xab900828] dvdnav demux debug: - cell_length=17420400 [0xab900828] dvdnav demux debug: - pg_length=17420400 [0xab900828] dvdnav demux debug: - pgc_length=221220000 [0xab900828] dvdnav demux debug: - cell_start=180280800 [0xab900828] dvdnav demux debug: - pg_start=180280800 [0xab900828] dvdnav demux debug: DVDNAV_SPU_CLUT_CHANGE [0xab900828] dvdnav demux debug: DVDNAV_SPU_STREAM_CHANGE [0xab900828] dvdnav demux debug: - physical_wide=128 [0xab900828] dvdnav demux debug: - physical_letterbox=128 [0xab900828] dvdnav demux debug: - physical_pan_scan=128 [0xab900828] dvdnav demux debug: buttonUpdate not done b=3 t=1 [0xab900828] dvdnav demux debug: DVDNAV_AUDIO_STREAM_CHANGE [0xab900828] dvdnav demux debug: - physical=0 [0xab900828] dvdnav demux debug: buttonUpdate not done b=3 t=1 Best regards, -- Tuomo Sipola tuomo.sipola(a)iki.fi

canonical GUI viewer
by Roger Pack 28 Apr '14

28 Apr '14

As a note, it might be nice to have some type of viewer "example/demo" in the source code [like one that wraps libav/SDL for displaying]. Just to make it easier for people to get their feet wet with the source. -roger-

dvdnav_describe_title_chapters
by Mickaël Guerin 21 Apr '14

21 Apr '14

Hi, XBMC is using dvdnav to get DVD playback. I'm working on extending chapters support, so I need to use the method dvdnav_describe_title_chapters. But when I try to free the *times array, I get an exception. Some google searchs, and my conclusion is that C compilers are different, so free() on xbmc side don't work with the calloc() of the dvdnav dll. I add a dvd_free(void* pdata) method on dvdnav (that just call free(pdata)) and now it's working. So, do you have any suggestions to make the dvdnav_describe_title_chapters usable, for every on who use it? Or maybe I made somethings wrong... thanks

Trying to get volume id of dvd. But not sure how?
by pauline martin 14 Apr '14

14 Apr '14

Hi, I am trying to fix a broken application and I am having trouble with figuring out how to fix it's method of getting the name of the dvd. It used to use hal for this, but I would like to switch it to depending on libdvdnav/libdvdread for it. The best that I can figure out is that I am supposed to use this->vm->dvd_name to get it, but I am not sure exactly on how to implement it in the C++ code. I have also seen some stuff that goes somthing like: info->tt_srpt but I can not find anything that gives me the answer I am looking for. I can get the number of titles and stuff like that but nothing that even remotely comes close to giving me the volume id of the dvd. Is this possible? -- pauline123
